Regular transfusions in thalassaemia: the schedule | CION Cancer Clinics
Most people with thalassaemia major need a blood transfusion every two to five weeks, often every three or four. The gap is set by the haemoglobin measured just before each transfusion, with a usual target of 9.5 to 10.5 on the g/dL scale, and by weight, spleen size and heart health. This page explains how the schedule is decided, what a transfusion day involves, and what it cannot tell you about your own child. At CION Cancer Clinics, our haematologist cares for anaemia, bleeding, clotting and inherited blood disorders, with ArogyaSri, CGHS and cashless insurance accepted.

The short answer
How often does a child with thalassaemia major need blood?
Most children and adults with thalassaemia major have a transfusion every two to five weeks. For many families in Telangana and Andhra Pradesh the rhythm settles at every three or four weeks. The exact gap is set by the haematologist from the haemoglobin measured just before each transfusion, not from a fixed calendar.
Why the schedule is regular, not "when the child looks pale"
Guidelines aim to keep haemoglobin, the part of the red cell that carries oxygen, from ever dropping low. When it stays in a steady range, a child grows better, has more energy for school, and the body stops trying to make extra blood of its own. That extra effort is what widens the bones of the face and swells the spleen. Waiting until a child looks pale or tired means waiting too long.
When the schedule usually begins
Regular transfusions are usually started in early childhood, once thalassaemia major is confirmed and the haemoglobin has stayed low on repeat tests. International guidance uses a level below 7 (in g/dL) on two separate checks as one of the reasons to begin, alongside poor growth or other signs. Your haematologist weighs all of these, not one number.
Laboratory reference ranges differ, and a single result is always read alongside symptoms and repeat tests.Your own interval
What decides the gap between two transfusions?
Two children with the same diagnosis can be on very different schedules. These are the things your team is looking at.
The haemoglobin before each transfusion
This is the main guide. The team aims to transfuse before it drops below a target range, usually 9.5 to 10.5 on the g/dL scale your report uses. If it keeps arriving lower, the gap is shortened or the volume changed.
Body weight and growth
The amount of blood given is worked out from weight. As a child grows, the volume per visit rises, and the interval may be adjusted at the same time.
The size of the spleen
An enlarged spleen breaks down red cells faster, so the blood lasts less time.
Signs the team watches for
- Needing blood more and more often
- A swelling felt under the left ribs
Heart health and other conditions
If there is strain on the heart, a higher target and a different rhythm may be chosen. Infections and fever between visits can also pull the haemoglobin down early.

Ask an oncologistOn the day
What happens on a transfusion day?
-
A blood sample, often the day before
A sample is taken to check the haemoglobin and to cross-match, which means testing that the donor blood is compatible with your child's blood. Many centres do this a day earlier so the unit is ready.
-
Checks before the drip starts
Temperature, pulse and blood pressure are recorded. The nurse and a second staff member check the name and the blood unit label together. Tell them about any fever, cough or loose motions since the last visit.
-
The transfusion itself
Blood runs slowly into a vein, usually over three to four hours for each unit. The first minutes are watched most closely. Children can read, watch something on a phone or sleep.
-
Going home
Most children go home the same day. Before you leave, write down the haemoglobin before transfusion and the date of the next visit.
-
The weeks in between
Normal school, play and food. Chelation medicine, which removes the extra iron that transfusions leave behind, continues as your haematologist has prescribed.
!
When not to wait for the next date
If, during or soon after a transfusion, your child has a high fever with shivering, trouble breathing, chest or back pain, a rash spreading fast, or passes dark red or brown urine, tell the nurse at once. If you are already home, go to the nearest emergency department or call 108. Do not wait to see if it settles.

Commonly believed
What do families often get wrong about the schedule?
"If we stretch the gap, there will be less iron."
Letting haemoglobin fall low does not solve the iron problem. The body then makes more of its own faulty blood, absorbs more iron from food and strains the heart. Iron is handled with chelation, not by skipping blood. Any change to the schedule is the treating team's decision.
"She looks fine, so she does not need it this month."
Children adapt to low haemoglobin and often look well until they are quite low. How a child looks is a poor guide. The number measured before transfusion is the guide.
"Blood from a relative is safer."
Blood from close family is not safer and can cause problems if a transplant is considered later. Screened blood from a licensed blood bank, matched by the lab, is what guidelines recommend.
"More blood each time means fewer visits, so it is always better."
Too high a haemoglobin after transfusion makes the blood thick and loads more iron. The volume and gap are balanced together for your child's weight and heart.
Living with it
How can you fit the schedule around school and work?
- Ask whether the sample can be taken the day before, so the transfusion day is shorter
- Ask for the same weekday each cycle, so school can plan around it
- Keep one notebook with every date, haemoglobin and blood group
- Carry the last report when you travel, in case blood is needed elsewhere
- Tell the school teacher which day your child will be away
- Book the next visit before you leave the day-care unit
Being straight with you
Who does this schedule not fit, and what can this page not tell you?
This page describes the usual pattern for thalassaemia major. It cannot tell you what your own child's gap should be. That comes from the haemoglobin trend, weight, spleen and heart, reviewed by the haematologist over several visits.
People who may not need a fixed schedule
People with thalassaemia trait do not need transfusions for the trait. Many people with thalassaemia intermedia need blood only now and then, for example during an infection, pregnancy or a growth spurt. Some later move to a regular schedule. The decision is made on how the person is growing and feeling, not on the name of the type alone.
When the schedule may change for good
A splenectomy, which is surgery to remove the spleen, can lengthen the gap in some people. A successful stem cell transplant can end the need for transfusions, but it suits only some people and is done at specialised transplant centres. CION's haematology team can review your child's records, discuss the case at a tumour board and help you reach the right centre.
Never shorten, lengthen or skip a transfusion on your own. Talk to the treating team first.Questions we are asked
Common questions about the transfusion schedule
Why does my child need blood more often than last year?
The usual reasons are growth, a spleen that is getting bigger, or an infection. A growing child needs more blood per visit, and the team may shorten the gap or raise the volume. Bring your notebook of past haemoglobin values, because the trend over several months tells the haematologist far more than one visit does.
Can we delay a transfusion by a week for an exam or a wedding?
Ask the treating team before the date, not after. Sometimes the visit can be moved a few days earlier instead of later, which keeps the haemoglobin from falling. Do not simply stay away. A planned change made with the team is very different from a missed transfusion.
How long does one transfusion visit take?
Plan for most of a day. The transfusion itself usually runs over three to four hours for each unit, and checks before and after add time. If the sample and cross-match are done the day before, the visit is shorter. Ask your centre how they organise it.
Will the schedule ever stop?
For most people with thalassaemia major, transfusions continue through life. A successful stem cell transplant is the main situation in which they can stop, and it does not suit everyone. Newer treatments are being studied. Ask your haematologist whether any of these options could apply to your child.
Does the blood need to be special?
Guidelines recommend blood that is matched carefully and has most white cells filtered out, called leucodepleted blood. This lowers the chance of fever reactions. Fresher units are usually preferred. Ask the blood bank what they provide, and keep a record of your child's full blood group and any antibodies found.
What if we miss a transfusion?
Call the treating team as soon as you can and arrange the earliest possible date. Watch for breathlessness, unusual tiredness, a racing heart or a very pale child. If any of those are severe, go to the nearest emergency department. Do not try to make up for it with extra blood later without the team's advice.
Can adults with thalassaemia keep working on this schedule?
Yes, many do. Ask for a fixed weekday or a weekend slot if your centre offers one, and arrange the sample the day before. Keeping haemoglobin in the target range generally means more steady energy between visits, which makes a working week easier to manage.
Is transfusion covered by any scheme?
Many state and central programmes support thalassaemia care, and Aarogyasri, CGHS, ECHS, EHS, PM-JAY and cashless insurance may cover parts of it. Rules differ between schemes and change over time, so check the current entitlement. Our helpline can tell you what applies to your card.
